BOLT.

To all whom it may concern Be it known that I, Fnnonrc D. OGDEN, a citizen of the United States of America, and a-resident of Bayonne, county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Bolts, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to anchor bolts, and particularlyto the type of anchor bolt comprising two parts of such form that in one position thereof the head portions may be inserted through a' hole of such size that when the parts are readjusted to their final position the head will be prevented from returning; through the said hole. This style of bolt is particularly adapted to sheet metal and other work wherein 'ready access cannot be had to the rear thereof. An example of this is readily found in sheet metal ceiling construction.

My invention consists in providing the members of such a bolt with a lateral projection such as will constitute an abutment to rest against the front face of the part to which the bolt is applied, and against the opposite face of which the head portions of the members bear.

The objects of my invention are first, to prevent the bolt from accidentally slipping clear through the hole and becomin 0st; second, to hold the bolt steady while t e nut or other portion for engagement with the stem is being applied thereto, and third, to permanently steady the bolt and lend rigidity thereto in use, I

My invention also consists in certain novel features of construction such as will be fully pointed out hereinafter, and in order-that my invention may be thoroughly understood, I will nowproceed to describe "certain structures constitutin thereof, having reference to t e accompanyembodiments ing drawings llustratin the same, and will then point out the nove features in claims.

In the drawings: Fi re 1 is a view in side elevation of an anc or bolt constructed in accerd ce ith my in ention; howing Specification of Letters Patent. Patehted J 1111617, 1913, Application filed January 28, 1910. Serial No. 540,485. '7 v i I the same as applied in use, the parts engaged by the bolt and a nut upon the bolt being shown in vertical transverse section. Fig. 2 is a detached view side elevation of the bolt and nut, thepoint of View 5' at right angles to the point thereof bein of view of Fig. 1. Fig. 3 is a viewpartly in plan and partly in horizontal section of the bolt. Fi iis a yiew of a slightly modified form of bolt. Fig. 5 is. atop view Of the same. Fig. 6 is.,a view in side elevation similar to Fig. 1, of a further modification. Figs. 7 and 8 are views in side elevation at right angles to each other, of an eye bolt'of the anchor type, and also constitnting an embodiment of my invention. v,

The bolt comprises two complementary members conveniently of substantially L- shaped form, each comprisingan arm 10 and an arm 11 at an angle thereto. The arms 10 are arranged to lie side by side with each other when the bolt is in use, to form a stem, while the arms 11 are arranged to. project laterally in opposite directions toform a head. In the form of bolt shown in Figs;

l to 6 inclusive the two members arecomposed of material which is substantially semi-circular in contour, theflat sides. thereof being against each othei and the exterior port ons are screw-threaded so that the stem as a wholeis adaptedfor (to-engagement with a threaded nut.j12. The

members are insertedthrough a hole 13 in against each other, after the head has been A,

so inserted. The stem portions 10 a'r provided'with lateral pro ections 15 adgacent the head portions 11 but spaced therefrom a distance preferably equal to. about the thickness of the structure '14 with, :which A the bolt'is intended tobe employed, ,wheiieby when the said bolt is eliil'plgyed the adjaclejit faces of the said lateral projections'hfidth head portions may. engageop'posite Si the said. structure. These projections will act to prevent the bolt from passing clear through the hole 13 when being inserted therein, and will tend to hold the two members firmly and in proper relation with respect to each other while the nut 12 is being applied. This will facilitate the application'of the nut and will also prevent the possibility of the parts being improperly adjusted when the nut is applied,-that is to say, it will prevent one'member being moved longitudinally with respect to the other, such as might readily happen without these projections, under which circumstances but one of thehead portions would be in engagement with the-structure 14. The presence'of these projections also, of course, lend rigidity to the structure, as a whole, in that they tend to steady the parts independently of the nut. The hole 16 in thepart l'? to be secured to the structure l lis, of course, made of a suflicient size to receive these projections 15, as will be well ,understood. These projections may be conveniently formed by ofi'setting a portion of the metal of the stem, and three modifications of this are shown in the drawings. In Figs. 1, 2 and 3 the projections are formed by pinching the-stem portions at right angles to their surfaces, thereby causin the pinched portions to extend in the direction of the flat reference to the drawings.

ed to receive a nut. In this case thetwo members are, of course, kept together by some part such as a hook or the like which engages the ring-like portions, the lateral projections 15 acting to steady the device and to prevent the parts from getting out of adjustment.

WVhat I claim is: 1. A fastener comprising two complementary members each comprising a stem' portion and a head portion, and provided with a lateral projection upon the stem in proximity to the head portion, but spaced therefrom, whereby the said projection and head portion may, engage opposite sides of a. structurewithwliich the bolt is to be employed when it is so employed.

'2. A bolt comprising two complementary members each comprising a threaded stem portion and a head portion, and provided with a lateral projection upon the stem in proximity to the head portion, but spaced therefrom, whereby the said projection and head portion may engage opposite sides of a structure with which the bolt' is to be employed when itis so employed.

34A fastener comprising two L-shaped members, onearm of each member adapted to lie side by side with the corresponding arm of the other member to constitute a stem, and the other arm adapted to project oppositely to form a head, the first said arms being provided each with a lateral projection in proximity to, but spaced apart from, the arms constituting the head, whereby the said projections and the said head may engage opposite sides of a structure with which the bolt is to be employed when it is so employed.

4. A bolt comprising two L-shaped members of semicircular contour in cross section, one arm of each member adapted to lie with its flat side against the flat side of the corresponding arm of the other member, the said arms being screw-threaded on their curved sides whereby they together constitute-a screw threaded stem the-other arms being arranged to project oppositely to form a head, each of the first said arms being provided with a lateral projection in proximity to but spaced apart from, the arms constituting the head, whereby the said projection and the arms constituting the head may engage oppositesides of a structure with which the bolt is to be employed when it is so employed.

, 5. A fastener comprising two complementary members each comprising a stem portion and a head portion, and provided with a lateral projection upon the stem in proximity to the head portion, but spaced therefrom, whereby the said projection and head portion may engage opposite sides of'a structure with which the bolt is to be employed when it is so employed, the stems having recessed portions corresponding to the laterally projecting portions.

6.- A fastener comprising two complementary members each compr sing a stern portion, and a head portion, the stem portion having a part thereof laterally offset in proximity tothe head-portion, whereby the said lateral oflset may engage the side of a structure opposite to that engaged by the head portion when the said bolt is employed in use.

7. A fastener comprising two L-shaped -members of semicircular contour in cross section, one arm of each member adapted to lie with its flat side against the flat side of the again in proximity to, but spaced apart angular arms, M the two members being from, the arms constituting the head, to conturned in opposite dlrectiona.
